Faulty Temperature Sensor

This week, I was working on a weather balloon payload. Here, I tested temperature sensors connected to a portable circuit board: copper boards with copper shapes glued to an insulator replacing wires in a circuit (instead of wires, circuit boards use paths to connect electrical components, so the flow of electricity gets from one electrical component to another). However, the temperature sensor, AKA sensor temperature sensor 2, in port 0 was faulty. I switched the sensor from port 0 to port 3 to see if the issue was the port and concluded that the port was not the issue. I also concluded that the sensor itself was the issue and not the wire because if the wire was the issue, then the sensors would display no data; instead, the volts would be 0. To fix the issue, I soldered on a new sensor as seen below.


I cut the wire to get rid of the broken sensor; since out of the two sensors on the payload this was the one going on the inside, it did not hurt to shorten the wire since it did not need to be long like the outside sensor. After cutting, I put the black heat shrinking pads on each wire and put one big heat shrinking pad to hold all three wires. The heat shrinking pads are for the wires to avoid direct contact with each other at the tips. I then soldered the correct tip of the wires with the correct pins on the sensors. Soldering is melting solder using heated iron to attach certain objects. After attaching the wires with the pins, I slide the black shrinking pads to the top and used the heating iron to shrink the shrinking pads to hold the wires tight. Note that although the heating iron reaches 800 degrees Fahrenheit, manufactures design the sensor pins and wires to withstand the heat, so the risk of damaging the pins and the wires was low. After soldering, I was finished and got new data. This time, the data was with a hot heating pad and an ice pack. I compared the data with another working sensor and concluded that the new sensor worked!

Weather Balloon Spring Flight

 Weather Balloon Spring Flight This semester my team flew an RF receiver, CO2/ humidity sensor, Geiger Counter, seeds, a peep, and the old sensors from last semester (temperature, accelerometer, and pressure sensor). The RF receiver was to measure the strength of the Radio Frequency. The CO2 and humidity sensor are self-explanatory. The Geiger Counter (radiation sensor), temperature, and pressure coincides with the seeds; the Garden Cress seeds grow within 2 weeks, so we wanted to see which of the three variables that could affect it (radiation, temperature, and pressure) would and how. The old sensors were pre calibrated and ready to go from last semester. I do not know much about the RF receiver's calibration since another team member worked on it. The Geiger counter required calibrating with the Geology department to borrow a radioactive sample rock. The CO2 and Humidity sensor required calibrating through a separate CO2 and Humidity sensor (the separate sensors were pre-calibra...

System Block Diagrams Introduction Week 5

  Open Loop vs Closed Loop Systems For this week I chose system block diagrams because my ECE 103 class and, moreover, my ECE 294 class use system block diagrams, and people, including me, are unfamiliar with them, so I chose to research system block diagrams. Differing block diagrams are open loop and closed loop systems. Both, open loop and closed loop systems, have similarities. Any control system will take and process an input and generate an output. Internally, control systems are divided into two sections: the controller section and process section. The controller section controls the amount of input required to process an input. The process section processes the input to generate the output. Despite similarities, open loop systems have unique characteristics. Regarding open loop systems, the reference point is independent to the output. No feedback signal that indicates how to vary the input to get the desired output exists. For example, a toaster does not know when the brea...
